(a)0.016
(b)1.6
(c)0.16
(d)Data inadequate
Answer
Answer (as printed): B
Explanation
Let the body weight be $x \mathrm{kg}$. Then, Weight of skin protein in the body $$\begin{aligned} & =\left\{16 \% \text { of }\left(\frac{1}{10} \text { of } x\right)\right\} \mathrm{kg}=\left(\frac{16}{100} \times \frac{1}{10} \times x\right) \mathrm{kg} \\ & =\frac{2 x}{125} \mathrm{kg} . \end{aligned}$$ ∴ Required percentage $$=\left\{\left(\frac{2 x}{125}\right) \times \frac{1}{x} \times 100\right\} \%=\frac{8}{5} \%=1.6 \% .$$
